For the daily and attack positions of HMS P 35 during this patrol see the map below.

(5)

17 Jan 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) torpedoed and sank the Italian salvage vessel Rampino (301 GRT, built 1909) north-north-east of Sousse, Tunisia in position 35°59'N, 10°46'E.

Umbra picks up the Rampino's sole survivor.

(All times are zone -2)
0311 hours - A low dark shape was sighted ahead. It was thought to be a u-boat. Started attack.

0320 hours - In position 35°59'N, 10°46'E fired three torpedoes from 1500 yards. Dived on firing. One hit was obtained.

0330 hours - Heard HE of a small patrol vessel stopping and starting. This soon turned away and retired bearing 080° and HE soon faded.

0636 hours - Surfaced near the position of the attack.

0800 hours - Sighted a raft with one survivor. Picked him up. Another raft was seen but it was empty.

0839 hours - Dived in position 35°59'N, 10°48'E.

According to the survivor Rampino had a crew of 15 on board and was en-route to Pantelleria. (5)

20 Jan 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) attacked two merchant ships in a convoy about 5 nautical miles North of Kuriat with four torpedoes. No hits were obtained. [The targets have not yet been identified.]

(All times are zone -2)
2100 hours - Sighted many lights in the direction of Monastir. Closed.

2126 hours - The lights were seen to be ships.

2146 hours - Reduced to slow speed. Six ships fully illuminated were counted. Their course was 090°. It was estimated that this convoy must have been outside French territorial waters while crossing the Gulf of Monastir and would pass 2 to 3 miles North of Kuriat. They were proceeding to the Eastward and could only leave French territorial waters if they were not already outside them. If they were to turn to the South after rounding Kuriat they would cross latitude 35°46'N south of which they were open to attack irrespective of whether they were in French waters or not. It was therefore decided that if they were French they were proceeding or about to proceed illegitimately and that it was possible they were Italians masquerading as French. It was decided to attack.

2149 hours - In position 35°55'N, 11°02'E fired two torpedoes at the leading ship, the second largest. Range 4000 yards.

2150 hours - Fired two torpedoes at the second ship in line, the largest. Range 4000 yards.

2151 hours - Dived and altered course to Starboard. All torpedoes missed as the range was most likely underestimated. Set course to the North-East. (5)

22 Jan 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) ended her 2nd war patrol (1st in the Mediterranean) at Malta. (5)

1 Feb 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) departed Malta for 3rd war patrol (2nd in the Mediterranean). She was ordered to patrol off Kuriat.

As no log is available for this period it is not possible to display a map of this patrol. (5)

3 Feb 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) torpedoed and damaged the Italian merchant Napoli (6142 GRT, built 1941) about 30 nautical miles east of Sousse, Tunisia. [Napoli had sailed from Tripoli for Italy but on 30 January had broken her propeller’s axle and had to drop anchor at Mahedia. Because of the heavy seas, attempts by her escort the torpedo-boat Orsa to tow her had come to nought. On 2 February, Orsa was relieved by the torpedo-boat Procione and the auxiliary Giasone.] The ship was beached and destroyed by aircraft on the 11th.

(All times are zone -2)
1526 hours - Sighted a merchant vessel of about 6000 tons anchored in position 35.30'N, 11.06'E.

1533 hours - Sighted an Italian torpedo boat of the Spica-class patrolling close inshore. Started attack on the merchant vessel.

1637 hours - Fired one torpedo at the merchant vessel from 2600 yards. It missed.

1702 hours - Fired another torpedo at the merchant vessel from 2400 yards. It hit. The merchant vessel was seen to be down by the stern and listing to starboard afterwards.

1725 hours - The torpedo boat counter attacked. 8 Depth charges were dropped but these did no damage.

According to Italian sources the Napoli was anchored there because she had suffered engine failure while en-route from Tripoli to Trapani on 30 January. She had been towed to the position she was anchored in on the 31th. The ship was finally destroyed in an air attack on 11 February 1942.

[Napoli was hit astern and damaged, five were wounded by the explosion. Giasone took her in tow toward Sousse but after a few miles, she had to be beached the following day in 35°27'N, 11°03'E.] (5)

13 Feb 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) ended her 3rd war patrol (2nd in the Mediterranean) at Malta. (5)

21 Feb 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) departed Malta for her 4th war patrol (3rd in the Mediterranean). She was ordered to patrol to the East of Tripoli, Libya to intercept an important enemy convoy.

As no log is available for this period it is not possible to display a map of this patrol. (5)

23 Feb 1942
In the evening HMS P 35 (Lt. S.L.C. Maydon, RN) is ordered to a new patrol position, South of the Strait of Messina. (5)

28 Feb 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) attacked a medium seized merchant vessel with two torpedoes about 10 nautical miles South-East of Catania, Sicily in position 37°22'N, 15°16'E. No hits were obtained. [The target has not yet been identified.]

(All times are zone -2)
0917 hours - Sighted smoke bearing 190°. Set course to intercept.

1012 hours - In position 37°22'N, 15°16'E fired two torpedoes at a 2000 - 3000 tons merchant vessel. Range was 3800 yards. A loud explosion was heard and the torpedoes were not heard to run anymore. The target made a dense cloud of black funnel smoke and made for Catania at increased speed. (5)

5 Mar 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) ended her 4th war patrol (3rd in the Mediterranean) at Malta. (5)

8 Mar 1942
While dived during daylight at Malta with half the crew on board, HMS P 35 (Lt. S.L.C. Maydon, RN) has her pressure hull pierced forward by accident. The tube space flooded. She tried to surface but failed to do so. She was then raised a few hours later and was docked for repairs.

27 Mar 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) departed Malta for her 5th war patrol (4th in the Mediterranean). She was ordered to patrol between Kerkenah and Lampedusa.

As no log is available for this period it is not possible to display a map of this patrol. (5)

30 Mar 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) investigated the wreck of Napoli she had torpedoed on 3 February. The vessel beached near Mahedia appeared abandoned and her guns removed and no further action seems necessary. (3)

4 Apr 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) attacked an escorted merchant vessel with 1 torpedo about 10 nautical miles North-West of Lampione in position 35°37'N, 12°09'E. The torpedo missed. [This was most probably the Italian transport Una (1397 GRT, built 1904) escorted by the German minesweepers R 6, R 10, R 11 and R 12. They had sailed from Trapani bound for Tripoli but stopped on the way at Lampedusa about three hours after this attack.]

(All times are zone -1)
1138 hours - Sighted smoke bearing 299°. Altered course to intercept, went deep and closed at full speed.

1155 hours - The target appeared to be a 3500 tons merchant vessel with an escort and accompanying aircraft. Altered course to close more quickly.

1228 hours - The target was now seen to be painted black and white. She was escorted by 4 E or R boats and aircraft. Enemy course was estimated as 160°, speed 8,5 knots, range 7500 yards.

1238 hours - The target was seen to have altered course to 130°. P 35 was now almost right ahead of her at a range of 3500 yards. Maneuvered to obtain a favourable attack position.

1250 hours - It appeared P 35's periscope had been spotted so Lt. Maydon went to 180 feet and altered course. No counter attack followed however.

1317 hours - Returned to periscope depth. Saw the target about 4500 yards away steering a course of 140°. The escorts were in station on each side of the target. P 35 was nearly right astern of the target, not a favourable attack position. Given the strong escort of the target it was decided to attack with 1 torpedo as it must have been a valuable ship and cargo for the enemy.

1319 hours - In position 35°37'N, 12°09'E fired no.1 torpedo tube. Range was 5000 yards. The torpedo missed. P 35 then retired from the area to the West. (5)

6 Apr 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) attacked an escorted merchant vessel with two torpedoes about 20 nautical miles West-North-West of Lampedusa in position 35°37'N, 12°12'E. No hits were obtained. [This was most probably the German Atlas (2297 GRT, built 1927) escorted by the torpedo-boat Perseo and the German minesweepers R 9, R 12 and R 14 bound from Trapani to Tripoli. Two hours before the submarine had observed three E-boats moving to the northwest, these were R 9, R 12 and R 14 who had sailed from Lampedusa to reinforce Atlas her escort. Curiously enough Maydon did not mention the presence of the E-boats during the attack. Perhaps they were not seen due to their low silhouettes and the probability that the target was very briefly observed with the periscope because of the presence of aircraft.]

(All times either zone -1 or -2)
1340 hours - Heard HE bearing 250°. Went to periscope depth and sighted masts on that bearing. Altered course to 200° to intercept and closed at full speed.

1414 hours - The target was seen to be a merchant ship escorted by a Spica class torpedo boat which was ahead of her. Turned to a 120 degree track and closed at full speed.

1430 hours - In position 35°37'N, 12°12'E fired two torpedoes from 3200 yards. Both missed. Went deep as aircraft were sighted and retired to the West. (5)

9 Apr 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) ended her 5th war patrol (4th in the Mediterranean) at Malta. (5)

14 Apr 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) departed Malta for her 6th war patrol (5th in the Mediterranean). She was ordered to patrol between Kerkenah and Lampedusa.

As no log is available for this period it is not possible to display a map of this patrol. (5)

18 Apr 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) attacked the Italian merchant Nino Bixio (7137 GRT, built 1941) about 40 nautical miles south-west of Lampedusa in position 35°05'N, 11°49'E. All torpedoes fired missed their target. [She was on a trip from Tripoli to Naples escorted by the destroyers Antonio Pigafetta and Nicolo Zeno.]

(All times are zone -1 or -2)
0630 hours - Sighted a 6000 tons merchant vessel escorted by two destroyers. Started attack.

0655 hours - In position 35°05'N, 11°49'E fired 3 torpedoes from 5800 yards. It was thought one probable hit was obtained but this was not the case.

0704 hours - The first pattern of 4 depth charges was dropped. After this attack only 2 more depth charges were dropped. None caused any damage.

0734 hours - Returned to periscope depth. Sighted the target bearing 338°. (5)

19 Apr 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) torpedoed and sank the Italian merchant Assunta De Gregori (4219 GRT, built 1914) about 20 nautical miles East-South-East of Mahdia, Tunisia in position 35°23'N, 11°23'E. [She was on passage from Sfax to Naples escorted by the torpedo-boat Castore (equipped with sonar).]

(All times are zone -1 or -2)
1550 hours - Sighted a merchant ship approaching from the Southward. Altered course to intercept.

1557 hours - Sighted a Spica class torpedo boat escorting the merchant vessel of about 4000 to 5000 tons. Also two aircraft were patrolling the area. Started attack.

1643 hours - In position 35°23'N, 11°23'E fired two torpedoes at the merchant vessel from 1100 yards. Both torpedoes hit the target. The torpedo boat dropped only 2 depth charges which caused no damage to P 35.

1730 hours - Returned to periscope depth. Saw the torpedo boat laying stopped to pick up the survivors of the merchant ship.

[Despite being equipped with sonar, the torpedo boat Castore who was leading ahead heard nothing and did not observe any torpedo track. Only the sound of a double explosion followed by the sight of Assunta di Gregori broken in two with her stern sinking vertically, signalled the attack. The torpedo boat turned back to pick 35 survivors and dropped two depth charges for intimidation purposes.] (5)

25 Apr 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) ended her 6th war patrol (5th in the Mediterranean) at Malta. (5)

3 May 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) departed Malta for her 7th war patrol (6th in the Mediterranean). She was ordered to perform a special operation on the NW coast of Sicily and if her object was not achieved to spend 24 hours on the Palermo-San Vito route to attack shipping. We do not know the exact details of her mission.

However the operation had to be abandoned as P 35 developed engine defects and had to turn back.

As no log is available for this period it is not possible to display a map of this patrol. (3)

6 May 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) ended her 7th war patrol (6th in the Mediterranean) at Malta. (3)

10 May 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) departed Malta for passage to Alexandria.

At 0417 hours, shortly after leaving harbour, five darkened vessels were observed and did not answer the challenge. P 35 opened fire with its Lewis gun. The Port Wireless Station ordered the submarine to cease firing. These were HMS Beryl, HMS Trusty Star and three others who were waiting for the arrival of HMS Welshman. P 35 had not been informed of their presence.

As no log is available for this period it is not possible to display a map of this patrol. (6)

19 May 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) arrived at Alexandria. (6)

6 Jun 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) departed Alexandria for her 8th war patrol (7th in the Mediterranean). She was ordered to give cover during convoy operations to Malta and took position in a line with three other submarines in the Ionian Sea. (HMS P 31 (Lt. J.B.de B. Kershaw, RN), HMS P 34 (Lt. P.R.H. Harrison, DSC, RN) and HMS Una (Lt. C.P. Norman, RN) (Lt. S.L.C. Maydon, RN) (cover of Operation VIGOROUS)).

For the daily and attack positions of HMS P 35 during this patrol see the map below.

(6)

15 Jun 1942
At 0645 hours HMS P 35 (Lt. S.L.C. Maydon, RN) fired torpedoes at the Italian battleship Vittorio Veneto. The torpedoes however missed their target. Position of the attack was 36°00'N, 19°06'E. [The squadron was led by the battleship Littorio with Vittorio Veneto next in line, they were in company with the heavy cruiser Gorizia, the light cruisers Giuseppe Garibaldi and Emanuele Filiberto Duca D’Aosta and three squadrons of destroyers. The heavy cruiser Trento had just been disabled by an aircraft torpedo and lagged behind with two destroyers.]

At 1151 hours HMS P 35 torpedoed and sank the Italian heavy cruiser Trento in position 35°55'N, 18°59'E. Trento was already damaged by a torpedo from a British Beaufort aircraft (217. Sqn. RAF based at Malta). [Trento was screened by the destroyers Saetta and Antonio Pigafetta.]

(All times are zone -3)
0540 hours - Heard HE bearing 320°.

0545 hours - Sighted two large vessels bearing 310°. Altered course to intercept and closed at full speed.

0555 hours - Started attack on two Littorio class battleships and two cruisers in line ahead. Enemy course was 175°, speed 26 knots.

0611 hours - Aircraft started a bombing attack. P 35 was about to fire torpedoes at a battleship. The Italians went all over the place and it was not possible to attack now.

0618 hours - The pandemonium had died down and two cruisers were seen approaching. Started attack on these.

0622 hours - The cruisers turned away.

0628 hours - The battleships were sighted again escorted by four destroyers.

0630 hours - It was thought that the cruisers were laying a smoke screen but it was now sighted that one of them was on fire. Started attack on the battleships.

0646 hours - In position 36°00'N, 19°06'E fired four torpedoes from 5000 - 6000 yards. After firing P 35 went deep. It was thought one hit was obtained but this was not the case.

0719 hours - Returned to periscope depth to find the battleships disappearing to the South in a haze of smoke. Sighted the burning cruiser bearing 263° with a destroyer on either side. Range was 5500 yards. The enemy was proceeding to the West at slow speed. Commenced reloading the torpedo tubes.

0816 hours - The destroyers came nearer forcing p 35 to go deep and to proceed to the North. This delayed reloading.

0915 hours - Returned to periscope depth to find the cruiser still on fire bearing 159°. The two destroyers were laying a smoke screen. The cruiser was a Trento class ship. Started attack.

1006 hours - In position 35°55'N, 18°59'E fired two torpedoes. Both hit. P 35 went deep. Seven depth charges were dropped close to P 35 but they caused no damage. The counter attack ended at 1040 hours. HMS P 34 (Lt. P.R.H. Harrison, DSC, RN) was approaching from the South saw the cruiser break in two and sink in three minutes.

1058 hours - Returned to periscope depth. Only the two destroyers were in sight picking up the survivors. Range was 4 nautical miles. P 35 retired to the South.

[The destroyers Saetta and Antonio Pigafetta picked up the survivors and the hospital ships Aquileia and Città di Trapani were directed to the scene to help with the search. In all 602 survivors were picked up from a crew of 1152 but many were wounded and some died later.] (6)

24 Aug 1942
In a signal timed 1750C/24, sent by Capt. 1, HMS Turbulent (Cdr. J.W. Linton, DSC, RN) and HMS P 35 (Lt. S.L.C. Maydon, RN) are ordered to patrol within 60 miles from position 35°45'N, 23°24'E. HMS Turbulent in sector 160° to 210°. HMS P 35 in sector 210° to 260°. (9)

26 Aug 1942
In a signal timed 1506C/26, sent by Capt. 1, it was stated that an enemy convoy had left the Gulf of Athens. HMS Turbulent (Cdr. J.W. Linton, DSC, RN) was ordered to patrol in position 35°07'N, 23°27'E and HMS P 35 (Lt. S.L.C. Maydon, RN) was ordered to patrol in position 35°39'N, 23°07'E. They were to arrive in their positions by 0300C/27. If nothing had been sighted by 0630C/27, HMS Turbulent was to proceed towards the Anti-Kithera Channel.

In a signal timed 1603C/26, sent by Capt. 1, it was stated that an enemy convoy made up of one merchant vessel and a destroyer had left Suda Bay. This convoy was expected to pass HMS Turbulent and HMS P 35 between 2300C/26 and 0200C/27. This convoy was not to be attacked as bigger ships had been reported coming south. The convoy in question was most likely the one made up of the Italian merchant vessel Dielpi (1520 GRT, built 1912) escorted by the Italian torpedo boat Generale Antonio Cascino. They had departed Suda Bay around 1205B/26.

In a signal timed 1915C/26, sent by Capt. 1, the submarines were informed that at 1130C/26, a convoy made up of a 7000 tons tanker and two 5000 tons merchant vessels had been seen 10 miles south of Piraeus. They had been escorted by two destroyers. The tanker was most likely the Italian tanker Giorgio (4887 GRT, built 1907) which had departed Piraeus around 0900B/26 for Tobruk. She was escorted by the Italian torpedo boat Partenope. No merchant vessels should have been with the tanker at this moment though. (9)

27 Aug 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) was informed through ULTRA of an important convoy from Piraeus for Libya. She was ordered to the approaches of the Antikithera Channel and came under the operation control of the First Flotilla.

HMS P 35 torpedoed and heavily damaged the Italian transport ship Manfredo Campiero (5463 GRT, built 1925) west of the Antikithera Channel in position 35°41'N, 23°01'E. She was part of a convoy from Piraeus bound for Benghazi and included the Italian merchant Tergestea (5890 GRT, built 1926), escorted by the Italian destroyer Nicoloso da Recco and the Italian torpedo-boats Climene and Polluce. Manfredo Campiero was beyond salvage and was scuttled by the Italians.

1235 hours - The merchant ship blew up and sank. The torpedo boat was seen to proceed to the North-East.

[Manfredo Campiero was hit by a torpedo aft and a second torpedo was observed missing her stern by about 10 metres. She began to burn furiously. The torpedo boat Polluce sent a boarding party of seven with fire extinguishers but she appeared beyond salvage. The torpedo boat finished her off by gunfire. Four had been killed or missing, 255 survivors were picked up including 37 wounded, one of them dying later. In the meantime Nicoloso da Recco and Climene hunted the submarine and dropped depth charges, the destroyer claiming a sinking.]

Shortly before 0500 hours a ship was heard sinking. When P 35 returned to periscope depth shortly after 0600 hours nothing was in sight.

[The convoy attacked by P 35 was made up of the above mentioned Francesco Barbaro (coming from Brindisi) as well as the Italian merchant Unione (6070 GRT, built 1942) (coming from Taranto). They were escorted by the Italian destroyers Giovanni da Verrazzano and Lampo as well as the Italian torpedo-boats Partenope, Clio, Lince and Aretusa. When Francesco Barbaro was torpedoed Unione made off escorted by Da Verrazzano, Lince and Aretusa. Lampo, Partenope and Clio remained with Barbaro.

Barbaro had been hit in the bow in the first attack, she was taken in tow but sank at dawn the following day. Of a complement of 278 (223 Italians and 55 Germans), 248 survivors were picked up (125 by Clio and 123 by Lampo), 30 were killed or missing.] (3)

Didcott both of SBS) in a folbot to destroy a railway to the North of Pizzo, Italy. They successfully landed but the presence of a sentry and extensive barbed wire prevented them from reaching the railway line and they abandoned the attempt. (3)

17 Nov 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) torpedoed and damaged the Italian troop transport Piemonte (15209 GRT, built 1918) 4 nautical miles bearing 310 of Capo Rasocolmo, Sicily, Italy in position 38°21'N, 15°28'E. [She was on passage from Palermo to Messina escorted by the torpedo boat Nicola Fabrizi escorted by a seaplane (Cant Z.501 no.1 of 189^Squadriglia).]

(All times are zone -1)
1207 hours - While in position 38°23'N, 15°28'E sighted a large column of black smoke bearing 250°. Closed to investigate.

1240 hours - The smoke was now seen to come from a two-funnelled passenger ship thought to be of 7000 tons. She was escorted by a Generale class torpedo boat and a flying boat. Enemy course was 078°. Started attack.

1316 hours - In position 38°21'N, 15°28'E fired two torpedoes from 3000 yards. Went to 120 feet after firing. After 2 minutes and 35 seconds a torpedo explosion was heard and HE of the target ceased. A counter attack with 2 bombs and 20 depth charges followed. The bombs were rather close but caused no damage. The depth charges were further away.

1334 hours - Heard faint HE, possibly the target under way again.

1428 hours - Returned to periscope depth. Sighted the torpedo boat bearing 189° about 4 nautical miles off. Two aircraft were also patrolling the area. P 35 went deep again and cleared the area to the North. [Piemonte was hit aft and beached near Cape Rasocolmo. The crew took to three lifeboats, they had three wounded. The seaplane dropped two bombs on the submarine. Fabrizi after dropping intimidation depth charges (30kg), dropped the more potent 100kg depth charges set to a depth of 50-75 metres) then combed the area with a towing mine but result was uncertain.] (3)

(All times are zone -1)
0930 hours - Sighted a small merchant vessel, estimated to be 2000 to 3000 tons, bearing 342°. She was proceeding close inshore south of Hammamet. Estimated enemy course was 250°. Altered course and went to full submerged speed to intercept further South on the coast.

0945 hours - Enemy course was now seen to be 235°, speed was 9 knots. The target was keeping very close inshore. P 35 proceeded to the South-West at full speed.

1057 hours - Turned to a firing course.

1100 hours - In position 36°14'N, 10°32'E fired 3 torpedoes from 4500 yards. A very heavy explosion followed after about 4 minutes. Another very slight explosions followed about 15 seconds after the heavy explosion.

1109 hours - Returned to periscope depth. All that was left of the target was a magnificent column of orange and white smoke rising to about 1000 feet in the air.

[The tug Vega was sailed to her assistance but Süllberg had already sunk.] (3)

11 Dec 1942
At 0835 hours (zone -1) HMS P 35 (Lt. S.L.C. Maydon, RN) picked up two German airmen from a dinghy in position 35°29'N, 12°03'E. (3)

13 Dec 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) attacked an old-fashioned merchant ship of 1500 tons but missed. This was the Italian Docilitas (1246 GRT, built 1900) who was on a trip from Trapani to Sousse.

Shortly afterwards P 35 torpedoed and damaged the German troop transport Macedonia (2875 GRT, built 1922) about 5 nautical miles north of Sousse, Tunisia in position 35°55'N, 10°38'E. The damaged German ship was beached and abandoned. She was on trip from Palermo to Sousse carrying 1000 tons of fuel for Panzers. She was in company with the German Jaedjoer (308 GRT, built 1937) who had joined from Trapani and they were escorted by the torpedo-boat Cigno. On the morning of the 13th, Jaedjoer had been lost of sight, Cigno had turned back and found her adrift as her engine had broken down. The torpedo-boat took her in tow and brought her to Ras Mahmur while Macedonia had continued independently. Cigno rejoined her only after she was hit by P 35.

(All times are zone -1)
1403 hours – Sighted masts and funnel of a small steamship, very close to shore bearing 285°, estimated course 160°.

1442 hours – In position 35°54'N, 10°39'E, fired two torpedoes aimed at the foremast and mainmast then altered course to starboard and dived to 45 feet increasing speed to clear the torpedo tracks.

1445 hours – Explosion (muffled) after 3m. 9s. Torpedoes missed probably due to an overestimation of speed. [Docilitas was missed and luckily for her, the appearance of another ship drew the attention away from her and she reached Sousse safely.]

1449 hours - Sighted a vessel bearing 327°. The enemy was seen to be a merchant vessel of about 3000 tons on a course of 152°. Started attack.

1522 hours - In position 35°55'N, 10°38'E fired one torpedo aimed at the funnel. 47 Seconds after firing the torpedo hit the target. The target was run aground to prevent her from sinking. She was down by the bow and listing to port. P 35 then withdrew to the Northward but remained in the area.

1615 hours - An Italian torpedo boar was sighted closing the target.

1651 hours - The torpedo boat went alongside the target as had been hoped. Unfortunately it was on the far side. It was decided to fire the last torpedo in the tubes at the merchant vessel hoping to finish this ship off and damaging the torpedo boat as well.

1653 hours - Fired on the torpedo at the merchant vessel from 4100 yards. Unfortunately it missed. Withdrew to reload a torpedo as fast as possible.

1746 hours - Completed the reload. Stalked the torpedo boat that was now stopped a little distance from the grounded merchant vessel.

1812 hours - When about to open fire on the torpedo boat it shifted position. As the torpedo boat shifted position several times it was not possible to attack.

1947 hours - By now the torpedo boat had obtained contact on P 35 which had gone to 90 feet. First 6 and then 3 depth charges were dropped in rapid succession. Minor damage was caused by these depth charges. No further depth charges were dropped.

[Macedonia had been hit and taken a list, the torpedo tracks had not been seen and it was believed that she had been mined. Cigno arrived on the scene to find her abandoned except for her captain and three crew members. The torpedo-boat took her in tow and asked Sousse for assistance. The tug Optimiste sailed but arrived too late, Macedonia had sunk in shallow waters (12 metres). At this time Supermarina informed Cigno that Macedonia had been the victim of a submarine and she was ordered to hunt it. It interesting to note that Naval Headquarters in Rome were more informed on the local situation than the participants themselves. They were often accused of interfering too much with operations but this time they were justified. At 1930 hours Cigno obtained an echo and at 1945 hours dropped a pattern of depth charges but then lost contact. It was assumed that it was a false echo and the chase abandoned.] (3)

15 Dec 1942
HMS P 35 (Lt. S.L.C. Maydon, RN) ended her 16th war patrol (15th in the Mediterranean) at Malta. (3)

27 Dec 1942

9 Jan 1943
HMS P 35 (Lt. S.L.C. Maydon, DSO, RN) torpedoed and sank the Italian merchant Emilio Morandi (1523 GRT, built 1904) about 35 nautical miles east-north-east of Sousse, Tunisia in position 35°58'N, 11°20'E. She was in company with the Italian motorized lighters MZ 727, 736, 744 and 755 on passage from Tripoli to Trapani.

(All times are zone -1)
1416 hours = Sighted a merchant ship bearing 190°. Enemy course was 345°. Altered course to intercept.

1440 hours - The target was a 2000 tons old-fashioned merchant vessel. She was Northbound and in ballast. She was escorted by 4 'F-boats' (Tank landing craft).

1514 hours - In position 35°37'N, 11°09'E fired a torpedo at the target from 1200 yards. Due to an error in drill the torpedo was fired to late resulting in a miss. Another torpedo was then fired but this one also missed.

1820 hours - Surfaced in position 35°49'N, 11°12'E and set off in pursuit.

2003 hours - In position 35°58'N, 11°20'E fired another torpedo from 600 yards. After 27 seconds it hit the target. P 35 dived after firing and retired from the area. No counter attack followed.

[Morandi sank in 12 minutes, the lighters were hampered by the bad weather but picked up 23 survivors and landed them at Pantelleria. The torpedo boat Partenope arrived on the scene of the sinking and searched for survivors but found none.] (3)

10 Jan 1943
HMS P 35 (Lt. S.L.C. Maydon, DSO, RN) attacked a small tanker with torpedo and gunfire off Kuriat. The tanker was able to escape into shallow water. This was most probably the water carrier Teodolinda (361 GRT, built 1925) in company with the tug R 97 / Genova (91 GRT, built 1918) escorted by the auxiliary schooner R 112 / Maria di Piedigrotta (62 GRT, built 1932). They were on passage from Tripoli to Trapani.

1343 hours - The smoke was seen to come from a small tanker of about 1000 tons. She was Northbound and close inshore. Altered course to intercept her in deeper water between Ras Dimas and Kuriat.

1440 hours - The tanker was seen to be escorted by a single masted auxiliary schooner armed with a small automatic gun forward and a small tug that was thought to be unarmed.

1502 hours - In position 35°41'N, 11°06'E fired one torpedo at the tanker. It missed.

1637 hours - Surfaced in position 35°49'N, 11°06'E and proceeded at full speed in pursuit of the target.

1641 hours - Opened fire with the gun from a range of 5000 to 6000 tons. The target fled into the Gulf of Monastir. P 35 was unable to follow in the shallow water. After about 20 minutes 43 rounds had been fired and at least one hit was obtained.

1710 hours - Dived and retired to seaward.

[The Italian vessels escaped damage.] (3)

11 Jan 1943
HMS P 35 (Lt. S.L.C. Maydon, DSO, RN) attacked a 2000 tons merchant vessel with one torpedo off the Gulf of Hammamet in position 36°26'N, 11°01'E. The torpedo missed its target. This vessel has not yet been identified.

Later the same day she attacked the Italian sailing vessels Nuovo Domenico I (25 GRT, built 1938) and Concetta Falco (152 GRT, built 1920) with gunfire in the Gulf of Hammamet in position 36°24'N, 10°43'E. The Nuovo Domenico I is damaged during the attack. [Italian sources just indicate that Nuovo Domenico I beached herself 2 miles NE of Hammamet on 10 January and was declared a total loss on 14 January. Concetta Falco reached Bizerta and had to undergo repairs, in May 1943 she was scuttled there.]

0704 hours - Sighted an object bearing 305°, altered course and increased speed.

0712 hours - Identified the target as a 2000 tons merchant vessel in ballast escorted by 2 auxiliary schooners.

0738 hours - In position 36°26'N, 11°01'E fired 1 torpedo from 3800 yards. As the ship changed course and manned her gun the torpedo was most likely spotted and evaded. P 35 now withdrew to the South before closing the coast.

---------------------------------------

1617 hours - Sighted two sailing vessels leaving Hammamet Eastbound. Closed to intercept.

1702 hours - Surfaced in position 36°24'N, 10°43'E and opened fire on both sailing vessels with Lewis guns and one the larger one also with the 12pdr deck gun. Range was 2000 yards. Both sailing vessels turned to the North-West and ran for the shore. The smaller beached herself. The crew of the larger one attempted to board two small boats but as the ship was still under way both capsized and the crew was seen to swim to the shore.

1712 hours - Range to the larger sailing vessel was now 1000 yards. She was abandoned and drifting ashore. Ceased fire. 24 Rounds had been fired for 5 hits. The larger sailing vessel was also on fire. P 35 then retired to the South to make for deeper water before diving. (3)

12 Jan 1943
HMS P 35 (Lt. S.L.C. Maydon, DSO, RN) attacked a large German landing craft with a torpedo off Mahdia, Tunisia. The torpedo ran under. This vessel has not been yet identified, the two small landing craft were probably F 211 and F 258 which operated in the area.

(All times are zone -1)
0943 hours - Surfaced in position 35°26'N, 11°07'E to engage, with gunfire, a vessel sighted earlier. Upon surfacing two small German landing craft were sighted as well as a another unidentified vessel with 'what looked like a u-boat conning tower'. It was decided to engage this vessel with a torpedo so dived again and closed.

0948 hours - Identified the target as a large 'Siebel ferry' (tank landing craft). Set the torpedo in No.4 tube to 4 feet. Continued to close to attack from close range.

1018 hours - In position 35°26'N, 11°06'E fired 1 torpedo from 500 yards. The torpedo ran under. All three landing craft went into Mahdia harbour. (3)

15 Jan 1943
HMS P 35 (Lt. S.L.C. Maydon, DSO, RN) encountered an enemy merchant vessel off the Gulf of Hammamet. Both ships then opened fire on each other. As the Merchants vessels gunfire was rather accurate P 35 dived to avoid being hit. P 35 later surfaced and set off to chase the enemy but she was unable to obtain a favourable attack position so the chase had to be abandoned. This was the old Italian steamer Gimma (1542 GRT, 1897) on passage from Sousse to Palermo.

15 January 1943
2155 hours - In position 36°20'N, 10°59'E sighted a ship bearing 320°. Went to night action stations.

2203 hours - Identified the vessel as a northbound merchant vessel. Altered course to the North and went to full speed to intercept.

2208 hours - The targets course was seen to be 055°. The target was thought to be of 2000 tons with 2 masts and a thin tall funnel. Commenced chase on her starboard quarter.

2230 hours - As we were gaining very slowly and our position was unsuitable for a torpedo attack, manned the 12pdr gun and a Lewis gun. Altered course to close.

2233 hours - The target must have sighted P 35 as she opened fire on the submarine. P 35 now also opened fire. Range was about 3000 yards. The enemy's shooting was very accurate and the action was broken off and P 35 dived at 2236 hours.

2311 hours - Surfaced and commenced chase.

2325 hours - The target appeared to have turned and to come towards. Dived with the intention to attack with a torpedo.

2340 hours - Lost sight of the target through the periscope. Heard no HE.

2341 hours - Surfaced in position 36°23'N, 11°09'E and again set off in pursuit.

[Gimma was armed with a 76mm and opened accurate and after the 8th round fire the submarine was forced to submerge.]

16 January 1943
